I completely understand! I have recently had similar experiences myself and it is the most incredible feeling and one I did not expect. I feel like most of the time I'm so hypervigilant and up in my own head trying to make up that "lost ground" from being trans that I sometimes can't enjoy the moment. When someone just tags you as female it's so refreshing, it's really given me an oppertunity to step back, relish who I am and see the progress I've made.
